Very proud of this work and all the efforts from my team and collaborators on this! You can now use DGRs for in vivo targeted hypermutagenesis in E. coli. We also included some early proof of concept in Yeast thanks to @seth-shipman.bsky.social !

Yesterday our paper "Intra-species competition combats vancomycin-resistant enterococci" was published online.
We found an enterococcal strain that can outcompete a VRE strain, but loses its potency when given with other non resistant Enterococci.
Here is a high res img from the battle in the gut:

Fantastic collaboration w/ @dbikard.bsky.social @audeber.bsky.social @rayanchikhi.bsky.social labs led by @jmouradesousa.bsky.social : We assessed the rates of variation of anti-phage systems in P4-like satellites and P2 helper phages. Quick conclusion: Huge variation! We focus on 4 key questions/5
β‘οΈ preprint from the lab! Bacteria have loads of antiviral defences in their mobile genetic elements (MGEs). So when MGEs move between bacteria, the defences move with them, generating a fast turnover of defences in bacteria. But what about the antiviral defence turnover in the MGEs themselves? π€

Conjugative plasmids as programmable platforms to combat antibiotic resistance and enable microbiome engineering.
such a cool story by Dorado-Morales and team! πͺ
A step toward rationally designed conjugative interventions for AMR containment and microbiome engineering.
Feedback very welcome!
π¬ New work from the Mazel Lab engineers programmable conjugative plasmids to selectively target MDR bacteria and the resistance plasmid pOXA-48, blocking its spread in complex communities.

π¨ New preprint π¨
How promiscuous really are conjugative plasmids, and what does that mean for plasmid co-occurrence?
A pleasure to collaborate with @craigmaclean.bsky.social on the first paper of my fellowship!

We found that conjugative plasmids can actively eliminate recipient bacteria that resist plasmid acquisition. π§΅
Big week: welcomed a new baby boy Harris Lopatkin, AND our PlasAnn paper is finally out: academic.oup.com/nar/article/... (obviously the first more important than the second π₯°). Currently on leave but if anyone has the need to annotate large plasmids, go check it out!
congraaats beeaaa!! lots of great things are going to come out of this π

Hot off the press! Our latest paper led by @fernpizza.bsky.social, understanding how plasmids evolve inside cells. These small, self-replicating DNA circles live inside bacteria and carry antibiotic resistance genes, but also compete with one another to replicate. 1/

Come and be my colleague at the Dunn School! Itβs a brilliant place to work and exciting to be building up our immunology team. Do apply. Do pass on the news ππ§¬π¦ π¬π§«
Exciting times ahead!
Today marks the first day of the Loeff Lab at Leiden University Medical Center in the Netherlands π³π±. Iβm thrilled to begin this new adventure and continue exploring microbial defense mechanisms and their applications through an integrative structural biology approach.
Happy to finally share this! Read here about the best strategy the the persistence of low-copy plasmids. @mariosanter.bsky.social @iwangtoknow.bsky.social doi.org/10.1038/s414...
Do plasmids evolve faster π, slower π’, or just like chromosomes π§¬?
In our new paper, we tackled this question using theory, simulations, bioinformatics, and experiments!
